Glossary
Automation system
An AS is a PLC (Programmable Logic Controller) which consists of at least one
CPU and various I/O modules, plus operator control and monitoring devices.
Chassis ground
The term refers to the equipotential bonding of all equipment parts that may not
carry a hazardous touch voltage in the event of faults.
Configuration
Refers to the arrangement of individual modules in a distributed I/O system.
Diagnostics
Refers to the detection, localization, classification, display and further evaluation
of errors, disturbances and messages.
Diagnostics provides monitoring functions that run automatically when the plant
is in operation. This increases plant availability by reducing commissioning and
down times.
Distributed I/O devices
Distributed I/O units are not installed in the PLC rack, but are rather distributed to
remote locations, e.g.:
•
ET 200M, ET 200S, ET 200X, ET 200L, ET 200eco
•
DP/AS–I Link
•
S5-95U with PROFIBUS DP slave interface
•
other DP slaves made by SIEMENS or third parties
Distributed I/Os are interconnected to the DP master via PROFIBUS DP.
